These days it is almost impossible to be competitive using a slow manual approach to fabricating, especially when manually measuring & laying out copes, then burning them by hand. Plus there is additional grinding and cleaning of the cope adding additional costs to the process.
This means you have way too many man-hours in each cut or cope. What you really need is a more economical, and more accurate solution that does your coping and notching cleaner and much faster, ensuring you make a larger margin on your bids.
Learn how the Ocean Liberator can make you MONEY by coping your pieces significantly faster and cheaper than doing it by hand or with a robotic plasma coper.
